The article says that the peak daily traffic for the subway was 5M. This is not exactly huge scale today. I've worked on systems that handle that many users every second (and yes, they were built on Kubernetes). I think it's likely that the whole system could run (from a resources perspective, if not from a reliability one) from a single commodity server today.

Put together, the daily weekday ridership is probably closer to ~14M, pre-COVID. And that's not including some of the knock-on computational costs, like the radio network that links the MTA's buses or the in-system transfer rules.
